| 摘 要： | 试验对红龙草在1层和2层遮阴处理下的生长状况进行了对比试验,结果表明:(1)红龙草为喜阴草本,在遮阴条件下生长良好。且1层遮阴处理下其植株的密度和高度增加幅度最大;(2)遮阴影响红龙草叶片颜色的改变。遮阴越强,红色叶片数量越多;遮阴越小,红色叶片数量越少,而绿叶数增多。红色叶片多集中生长于植株的上半部;(3)1层遮阴处理的红龙草其叶片数量增长幅度明显大于自然光照下或2层遮阴处理的红龙草植株。 |

| Abstract: | The growth performance of Alternanthera dentata under different shading treatments was studied in Guangzhou.The results indicated that (1)A.dentata was shade-tolerant and grew well under the shading conditions,and its density and height increased under one-layer shading treatment.(2)Shading treatment affected its leaf color.The number of red leaf increased along with the shading intensity and red leafs mainly at the top of plant.(3)The leaf number in one-layer shading treatment was higher than two-layer sha... |
